Got my HK's the other day and install them that night. Very easy install and quality of the pipes are excelent. Have put about fifty miles on my meanie sense and still looking good. The sound is, in my terms, LOUD ! I called HK to see if I had the most quiet baffle and they said yes. Don't get me wrong, I like the sound and may just have to get use to it. In the mean time I will be trying to come up with a fix, maybe a baffle between the existing baffle and Hardtip. Will keep the forum posted on progress.
